st: Weights in dataset

there are several weights in my dataset and I would like to use a few of
them for my analysis. I have been looking in the help if there is a
command on weights but just found the one where I can use weights as
options to other commands. But I would like to use the weight for all
following analysis instead for each individually as it is possible in
SPSS. Maybe someone knows a command. Thank you very much in advance.
